Some index managers will have to buy this monday morning in order to update their Q-50 Index funds. Should be good for a pop along with a possible upgrade from one or more of the 20 plus analyst that follow LULU. GL!
There does not appear to be any mutual fund based upon NASDAQ Q-50 Index solely. There is one ETF based upon this index: PNXQ which has net assets of $7.6M and only 7,951 shares traded on Friday. I doubt this will have any impact on the price of LULU.
